7 Application filed nine 6, 192 5. Serial No. 35,499.

This 'invention relates to .an improved 'faucet or drain device of simple and inexpensive construction,

- A variety of drain evices' are now available but most of them are composed of a multiplicity of expensive parts. Thus, many drains have a cone or a ground joint shutoff, or a packing .of some kind which very quickly wears out. On the other hand, the simpler devices are usually 'ill-fitted for quick control of the draining operation.

Nipples with threaded caps areused, but the l quid orgas can escape through the end .of

' nipple only when the cap is removed entirely. It'is often a difficult and messy job to remove and replace the cap, particularly vwhen the container is under pressure.

It is the object ofsthe invention to provide a drain comprising a minimum number of inexpensive parts and easily operablegases or to' facilitate the withdrawal of liquids from'containers. In the preferred form of the'invention, the improved drain is composed-of an ordinary pipe'nipple threaded at both ends, one end ofthe nlpple is designed to fit into an appropriately sized and shaped threaded hole in the container. drawn tightly into the container in such way as to avoid leaks. The other end of the nipple is threaded to receive a cap. A vent "'1 joint. The cap can be-made of metal and. 40

sha d to fit a wrench or even to be operat by hand. g

The length of the nipple, the location of I the vent, and the size of the cap are allso designed that the vent maybe fully opened without entirely removing the cap from the nipple. The threaded arrangement of these parts thus makes it very'easy to turn the cap back over the vent no matter how much pressure. is exerted on the escaping liquid or gas.

-It maybe desirable to have the drain constructed so that it is impossible to completely separate the cap from the nipple. This fea ture is articularly desirable where the drain device is to be 'used in connection with liquid or gaseou containers under high pressures,

The nipple can bev for example, a high pressure steam line; or where the drain is to be substantially foolproof. This is also fdesirable'if the drain cock is to be .used where it is accessible to children; The means for preventing the complete separation of the cap from the nipple may comprise a stem attached to the cap and extending into the'end of the nipple with a head which bears against a suitable shoulder when the cap is withdrawn to uncover the vent. within the nipple when the vent is opened and restsnugly against the restraining shoulder within the nipple. If the shoulder is properly positioned with respect to the The head may fit closely head of-the stem when the vent is completely 7 self will fit very snugly in the shoulder.

The preferred forms of the invention are illustrated in the accompanying drawing in which a Fig. 1 is a device.

Fig. 2"is a sectional view on the line 2-2 of Fig. 1 illustrating. the means to prevent the removal ofthe'cap, and also illustrating a modification in which deflecting means may be employed.

Referring to the drawing, 1 indicates the body of the drain. Anordin'ary metal pipe nipple with an axial passage will serve very well for this purpose. The end 3 is preferably provided with a tapered pipe'thread to fit into the liquid or gas container. The other end l of the nipple is likewise preferably provided with a tapered thread to fit the cap 5. The'end 4 containsthe vent 6,

side elevation of the drain which may be'of any diameter equal to or opened, the head serves to deflect the escapless than, the inside diameter of tlfe nipple.

This vent is situated with reference to the extreme end of the nipple so that the cap 5 may be unscrewed far enough to completely open the vent and yet have suflicient threads Ont e nipple endto prevent disengagement.

Ihe cap 5may be of any desirable construe 'tion either to be operated by hand or by the use of a suitable tool. Preferably, it is hexagonally shaped tofaeilitate theuse of 'a Wrench.

, equipped with a stem 7 will fit snugly upon As illustrated in Fig. 2, the cap 5 is having a head 8 .at the end thereof which fits very snugly in the nipple 1. The nipple 1 also has a shoulder 9 at the end 4. This shoulder. is fitted into the nipple end in any suitable man-' ner, preferably by welding. It has a hole through its center into which, and through which, the stem 7 may snugly fit as the cap 5 is moved. The length of the stem 7 may he designed in connection with the nipple, the shoulder, and the head8, so that when the vent 6 is completely opened, the head 8 the shoulder 9, to dethrough the ventand, prevent the movement of. any of the gas or liquid intov the disengaged portion of cap 5. Stem 7 can be screwed into the end of the cap as shown at 10. That portion ofthe sten'iextending flect the liquid or gas at the same time, to

beyond the cap may be upset upon the cap 5 to firmly rivet the-stem and cap together, and thus make a .non-leakable joint.

Fig. 2 also adjacent to vent 6 for deflecting any liquid which has a tendency to squirt to the side of the vent 6 as the cap 5 is unscrewed. Such escaping liquid is thereby illustrates the use of means 11' deflected toward the spot through'the vent would normally fall when the vent is completely opened.

Various changes can be made in the details of construction of the drain as described without departing from the invenwhere the lioluid escapingfrom the nipple including a stem extending through the cap, a shoulder on the nipple and a head on the stem adapted .to engage the shoulder.

2. A drain comprising a nipple having an axial passage and a lateral vent near one end thereof, a cap embracing that end of the nipple and movable relatively thereto to open and close the vent, and a deflector secured to the nipple adjacent to the vent.

In testimony whereof I afiix my signature.
